Hi guys, I’m very new to hack the box and I’m not sure how to connect to the challenge. If someone could point me in the right direction that would be much appreciated!
You press the ‘start’ button and then use something like netcat together with the hostname (docker.hackthebox.eu) and the port provided. However, that said, if you are new to hackthebox I suggest you try an easier challenge first.
Thank you @Xh4H for this challenge! It required a bit of basic socket programming before I was on my way to figuring out the flag. This is one of the rare few in the crypto category that has any relation and relevance to modern cryptography.
Can’t figure out what cryptosystem is in play here. I have a general idea of how to attack, but don’t know how to parse what I’m seeing in order to apply the attack.
Got it. This was very satisfying. To get traction you need to have some familiarity with what the typical crypto is for communication sessions. It’s basically an inference, especially since the language is used a bit loosely. (This was the hardest part for me! I went back and did research and did a few relevant exercises. Then I got hung up on parsing, which was not necessary.) Then you need to try to see if there are patterns or commonalities in what you see from instance to instance. Finally there is some simple math. Knowing how things are typically done is helpful. (fwiw I didn’t do any socket programming – nothing nearly that complicated)
@Xh4H ■■■!!! Really really nice challenge! I love these kind of math. I will respect you. That motivates me to get a higher graduation in informatics.
I used python to solve this challenge. The mathematics behind this topics is really interesting and understandable, but the programming-part was hard (for me…). I didn’t find online tools/online calculators.
edit got it it was really an intresting challenge its all about some basic mathematics knowledge that i was missing every time thanks for any one that helps me i was blind as usual hahah
